Abstract (en)
A method (700) for in-process monitoring of a 3D manufacturing apparatus (100) or quality control of a 3D manufactured structure (140) is provided. The method (700) includes a generating step (710) that generates an acoustic wave in the 3D manufactured structure (140). A receiving step (720) receives the acoustic wave with a microphone array (160). An analyzing step (730) analyzes a frequency spectrum of the acoustic wave. A determining step (740) determines if the frequency spectrum indicates a defect in the 3D manufactured structure (140).
